StreamWool Crewneck is a reversible wool sweater with a round neck. One side has a raised surface thanks to a knitting in various layers. The other side has a regular soft and flat knitting. The garment has double layers of WarmWool over the shoulders for best durability and protection when wearing a backpack. A single layer of WarmWool under the arms for best ventilation and comfort. Thumbholes at the cuffs minimize cold draughts around the wrists. The washing instructions are hidden in a pocket at the bottom of the arm.
